4) A 4 N force is used to compress water in a syringe that has a plunger with an area of 1 cm?. This pressure is released at the other end through an opening with a radius of 1 mm. With what velocity would the water exit the syringe? Assume no height change, and neglect viscosity. 5) If the water in #4 was shot out horizontally from a height of 1 m, how far would it travel before hitting the ground?

If a fluid's speed increases, what happens with its pressure and how do you know?
